Hi Sultan,

Yes you can use more than one extensions in your visualforce page. That extensions are separted by commas, There is no limitations for using extension. 
<apex:page standardcontroller = "Account" Extensions="TestClass1, TestClass2, TestClass3">

</apex:page>

Hi Sultan,

You can have only one Standard controller in your VF page but there is no limitation to the extensions, you can have multiple extensions to a controller.

Thanks,
